This book, which studies Barcelona's world of galleries, was born of a commission from the Art Barcelona association on the occasion of the XX anniversary of the creation of this group. The study is divided into three parts. The first two serve as an introduction and offer a reflection on specific episodes that constitute the background and points of reference for our contemporary framework. The first chapter reviews the origins and formation of the gallery institution in Catalonia. That is, the period that has, perhaps, been studied most, with the fundamental contributions of Joan Anton Maragall i Noble on the Sala Pares and Francesc Fontbona and Rafael Santos Torroella - among others - on the origins of the art market in Catalonia.
